What is this publication?
It is an informational letter sent to all known I-Trek owners that have
email addresses. Its purpose is to help owners of these wonderful but rare
motorhomes understand them better, and know how to fix most problems as
they arise. The information comes from owners who have had problems and
contribute to the infoletter the symptoms, causes and how they were
repaired. So, if you have a problem with your I-Trek, BE SURE to sit down
and review the Infoletters because it is likely the problem has been
encountered before and some owner has shared the information so you can
have an easier time fixing it. There is a helpful topic index [lower on
this page to help you find the topic you are interested in.] If you aren't
mechanically inclined, at least you can educate and supervise whoever is
accomplishing the repairs. PLEASE reciprocate and send Ken your
experiences with your I-Trek. Your writing doesn't have to be perfect.
Ken will edit it so you look good!
If your Isuzu Trek breaks
A money-saving hint: The first thing to do if your Trek
gets sick is to sit yourself down and read through ALL of the past newsletters.
Why? Because there is a good chance the problem has happened to someone else
and is written up in the newsletter, including the fix!
If your tranny acts up, first just pull over to a safe
place, shut off the engine after the cool down period, go drink a coke or
limeade for at least 5 minutes then start up and start on your way again. If
that doesn’t fix it, the battery disconnect Jim describes in newsletter #10 will
probably do it.
